GAR-COUPLING.

Specification of Letters Patent.

Patented Dec. 8, 1908. I

Application filed July 2, 1906. Serial No. 324,379.

To all whom it may concern:

Be it known that we, JAMEs TIMMS and JAMES O. TlMMS, residents ofColumbus, in

the county of Franklin and State of Ohio, have invented certain new anduseful Imlprovements in Oar-Couplings; and we do ereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in 'the art to which it appertains tomake and use the same. Our invention relates to improvements in carcouplings, the object of the invention be-' mg to provide an lmprovedlever constructed tomove the locking device 'to lock set posi tion andthen throw the knuckle open, and

v the invention consists .in certain novel features of construction andcombinations and arrangements of parts as will be more fully -vated.

hereinafter descri claims.

In the accompanying-drawings, Figure 1 is a view in vertical crosssection through the coupler showing the pin in locked position. Fig.21's asimilar view showing the pin lock ed and pointed out inthe set,the tail of the knuckle being omitted, and

Fig. 3 is a perspective view of a modified form of lever. I

1 represents a coupling head, 2 the tail of a swinging knuckle, and 3-the locking pin to lock the knuckle in closed position. The locking pin3, when in locking position'projects through an opening or housing 4 inthe bottom of the coupling head and is provided with a shoulder 5 toseat on a ledge 6 in the coupling head to support the pin in looksetposition when moved to this position by our 1m roved lever 7 as willhereinafter appear.

he lever 7 is fulcrumed between its ends to a depending lug 8 oncoupling head 1 and its weighted lower end projectsbelow the rounded. orbeveled lower end of pin 3, and this weighted end of the lever is curvedor inclined on its upper face where it contacts with pin 3, so that thelifting movement of the lever will not only elevate the pin but willalso exert cam action on the pin to force its shoulder 5 over onto ledge6 and compel the pin to assume its lock set position when ele- The upperportion of lever 7 above its ful crum which lies beside the side wall ofthe coupling head, is made with an arm or tongue 9 projecting throu h anopening in the wall of the coupling hem and into a recess 10 in the rearor back of the knuckle tail 2, and this armor tongue may projectlaterally from the lever ,to force the knuckle open. The

4 with an o 7 as shown at 9 in Fig. 3, to dispose the arm nearer thepivotal point of the knuckle so as to require but a slight movement ofthe lever u per end of lever 7 is connected in any desired mannererating rod or bar 11 extending to the side 0 a car in convenient reachof an operator.

The operation of our improvements is as follows :When the upper end oflever 7 is drawn back'by the rod or bar 11, the lower heavier end of thelever will be moved upwardly-to elevate the locking pin 3, and also byreason of the cam action of the lever against the lower end of thelocking in will move the pin laterally until the shou der 5 thereonrests on the ledge 6, thus supportin the pin in its lock set position..When the 00kmg pin is thus set, the knuckle may be opened by the subseuent separation of the cars. As the knuck e moves to its open position,its tail engaging a shoulder on the coupling pin moves the latterlaterally oil the ledge 6 and en ports the pin in its elevated position.W closed the coupling ported thereon, dro s in front of the tail of theknuckle and loc s the latterin its closed position. If the coupling bedisenga ed and 1t is desired to manually open the knuckle so as to be ina condition to couple, the cou ling pin should'be elevated as above expained, by an outward ull on rod 11 and upward movement of t e lower endof lever 7. After the pin has been seated 'on ledge 6, the bar 11 shouldbe pushed in thus reversing the direction of movement of the lever 7,and forcing the upper arm on tongue .9 into contact with the rear faceof the tail of the knuckle. This movement of the lever forces theknuckle to its open position. During its opening movement the knuckleremoves the pin from the ledge as aboveexplained and supports it in itselevated posltion until the knuckle has been.

turned to its closed position.

Manychanges might be made in the general form and arrangement of thepartsdescribed without departing from'our 1nvention and hence we wouldhave it understood that we do not restrict ourselves to the precisedetails set forth but consider ourselves at liberty, to make such sli htchanges and alterations as fairly fall within the spirit and scope ofour invention.

Tlaving fully described our invention en the-knuckle is again pin whichhas been sup-i adapted to engage the lower end of the locking device,and having a fixed arm near its other end to engage the tail of theknuckle,

the said lever adapted when moved in one direction to move the lockingdevice to a position where it will be supported and will release theknuckle, and when moved in the opposite direction to engage the knuckletail to open the knuckle.

2, The combination with a Janney type coupling, of a lever pivotedbetween its ends to the outside of the coupling and hav ing one integralend projecting beneath the locking device for moving the latter to :1,position where it will be supported i-lllll will release the knuckle,and an integr on the lever projecting through an r 5: in the side wallof the coupling and 121 m it recess in the knuckle tail in position toinvocthe knuckle open.

In testimony whereof, we have signed '1 his specification in thepresence of twr-t scribing witnesses.
